all the members of a species living in the same place at the same time
refers to the group in general and the size (number of individuals)
Answer the following in your notebook: Look at Figure 2 on page 212 in your textbook.
What are some ways that you or any scientist could describe the populations of these animals and how these populations function in an ecosystem?
How does a Population Grow?
Change in Population Size = Births - Deaths
Watch the video clip on Population Density:
In your notebook, briefly explain how you would determine the population density of people in this classroom.
Complete the population estimation section for both dates. Write down your estimates.
Discuss the questions with your partner. You do NOT have to write out your answers.
Complete the "Count the Boxes" section. Write down your estimate, but again, just discuss your answers to the questions.
Read page 213 in your textbook. Reproductive potential is the maximum number of offspring that each member of the population can produce.
This varies greatly among different species.
A bacterium can produce 19 million descentdants in a few days or weeks.
Animals have different strategies for maximizing reproductive success.
In your notebook, give examples of how animals maximize their reproductive success and discuss how the evolution of reproductive strategies in those animals relates to their parental behavior.
Read pages 214-215. Using figure 5 on page 214, answer the following in your notebook:
Describe what happens when a species, such as rabbits in Australia, are introduced into a new area and disrupt the ecosystem.
